NITAED STATES AEN FFQEG BENJAMIN F. SHEPHERD, OF PLEASANTVILLE, INDIANA.

HOISTING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 392,571, dated November 6, 1888.

Application filed February 9, 1888. Serial No. 263,538. (No model.)

To (rZZ 2071,0122 it may concern:

Be itknown that LBENJAMIN F. SHEPHERD, a citizen of the United States, residing at Pleasantville, county of Sullivan, State of Indiana, have invented a new and useful Hoisting Apparatus, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to improvements in hoisting apparatus.

lhe object of the invention is to provide a more ready and convenient means for taking off and putting on wagon-beds, for swinging horses or muleswliile shoeing also for swinging horse's"ofother'heavy animals while treating for a broken leg or other injury.

Vith this end in view the invention consists in the novel combination and arrangement of parts, as will be hereinafter described, and particularly pointed out in the claim.

In the annexed drawings, to which reference is to be had, and which fully illustrate my invention. Figure 1 is a side View of the apparatus, showing the attachment to frame of the rope,pulleys, gearing, clamps, and wagon-bed. Fig. 2 is a front view showing the gearing. Fig. 3 is a detail view showing the groove in the back of the screw to prevent it from turning. Fig. 4. is a sectional view on line 00 wof Fig. 2, showing the feathered bearing it.

Like letters refer to like parts in the several figures.

a represents the frame, and 0, m, n, and y the bearings, all made in one solid piece, with openings in 0 and g for shaft a2; also in m and a for the passage of screw s.

c is the crank attached to the shaft of the bevel-gear D, which meshes with the bevelgeared nut-wheel t.

f represents the frame, to which the apparatus is attached.

0' represents the rope; P P, the pulleys;b, the clamps, which are adapted to go under wagon-bed B.

9 represents a groove in the back part of screw 8, which works on a feather made in the back side of the bearings m and a to prevent screw 8 from turning.

The apparatus is operated by turning crank 0, thereby driving the bevel gear-wheel D and nut-wheel 15, thus causingscrew s to move up or down, accordingly as crank c is turned to the right or left. Rope r is attached to screw 3, and passes over pulleys P P, and is attached to clamps b, which are adapted to hold wagonbed B. When screw 8 moves up or down,wagon-bed B will be lifted or lowered.

, From the foregoing descriptions it will be obvious that the construction and operation of my device are simple and effective both in its adjustments and movements.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

A hoisting apparatus comprising the frame f, the frame a, provided with the bearings 0, y, m, andn',integral therewith, the latter two each having a feather, drive-wheel D, nut-wheel t, crank a, screw 8, provided with a groove, 9, rope r, pulleys P P, and clamps b, all constructed and arranged in the manner specified.

In testimony whereof Iaffix my signature in presence of two witnesses.

SHEPHERD.
